3 Claims.

This invention relates to portable toilet rooms and more particularly toan auxiliary cess. tank adapted to collect and temporarily retain themore solid parts of the refuse commonly deposited within the toilethopper. Ay generalobject of this invention is to provide improved meansin the form of an'auxilia'ry `cess tank secured below but inclosing thedrain spout of 'a portable'toilet in a manner'that' adapts saidl cesstank to collect and temporarily retain' the more solid parts of therefuse commonly deposited v within thehopper of said portable toilet.

A rspecific object of this'invention is toprovide improved means forconveniently controlling the removable bottom of an auxiliary cess tankwhereby said tank may be used to collect and retainthe more so-lid partsof refuse commonly deposited within the hopper of a portable toilet withwhich said tank 'is associated, and, vice versa, said controlling meansproviding for conveniently opening said bottom of said cess tank wherebysaid cess tank offers no obstruction to the flow of refuse commonlyflushed through said portable toilet.

Another specic` object of this invention is to provide 'improved meansfor controlling an auxiliary cess tank, designed tobe associated with aportable toilet, of such form that the operating handle of saidcontrolling means may be located l convenient to the hand of thecare-taker and out-of-the-way of the user of said portable toilet,whereby said handle may notbe disturbed by said user but may be quicklyand conveniently operated by said care-taker to close or open said cesstank.

' Anotherspecic object of this invention is to provide improved means inan auxiliary cesstank and controls of forms suitable to' be associatedwith standard forms of portable toilets, such as used in Pullman cars,other standard passenger cars, and house trailers, whereby the porter incharge of the particular vehicle may conveniently and quickly close saidauxiliary cess tank when said car stops at a station and/or open saidauxiliary cess tank when said car has moved away from said station.

Another object of this invention is to provide improved means in anauxiliary cess tank and controls in forms adapted to be installed onstandard vehicles Without interference with structural parts of saidvehicle.

Various other objects and advantages will be apparent as the nature ofthe invention is more fully disclosed.

In the accompanying drawings are shown the 2 novel features andconstruction of. one` embodiment ,of the device'according to the presentinvention:`

Fig; l, is a plan view of a portable toilet of common form showing thebottom of the accompanying auxiliary cess tank rotated into 'anoffposition as indicated by dotted lines:

Fig. 6 is an enlarged fragmentary view of an adjustment member, takenabove vand approximately along the line 6 6 of Fig. 5.

In the following description certain speciiic terms vare used forconvenience in referring to various details of the'invention. Theseterms, however, are to be given as broad an interpretation as the stateof the art will permit.

Referring now more particularly to: the accompanying drawings, thefollowing is a description Vthereof wherein like and correspondingparts` are designated by similar reference characters.

In `the' embodiment of the invention disclosed numeral I represents thewalls of a tubular auxiliary cess tank which incloses the drain spout 2of a portable toilet.v Said cess tank is secured tothe floor 3 of aportable toilet room, ona standard vehicle, by means of projections 4and bolts 5, and said cess tank is spaced below said iioor 3 by means ofspacers I5. Nearr the top of said cess tank I screen openings I permitexcess water to drain out, the more solid parts of the refuse commonlydeposited within the hopper 8 of a conventional toilet for vehiclesbeing retained within said tank I when the bottom 9 is closed. Saidbottom 9 is secured to a shaft I B by an arm 9a which pivots in a tubeII that is se* cured to projections I2 and I3 of said tank I. Said tubeII and shaft Ill extent approximately vertically but may be inclinedaway from said hopper 8 when necessary to avoid interference withexisting structures.

Shaft I0 and bottom 9 are operated by means of a lever I4 which isadapted to be operated by the foot of the porter in charge of saidportable toilet room. Said lever I4 is connected to the upper end ofshaft I0 in a common manner; the

produced by twisting a solid square bar, and when made slidable througha square hole as shown in the nut I1, Fig. 6, this provides a rotatingaction of said shaft I that closes and opens said bottom Q'Withtheupward and downward movement, respectively, of said shaft I0. A rollerrests Within the saddle of a rubber cushion 2l in a manner adapted tosupport the weight of said bottom 9 and conjunctive parts, and hold, byits resiliency, said bottom 9 against the lower end of said tank l. Saidrubber cushion 2i is ysupported by the base plate 22, and retainedbetween extensions 23, 24 of said base plate 22. Near the central partof said lever I4, downward extensions 34 retain a pin 35'. and saidroller 20 concentric with said pin 35 between said extensions 34. Saidextensions 2.3, 2.4 also retain the ends of said pin 35 which slidefreely .within vertical slots .cut within said extensions 23, 24. Saidlever IA is held in closed position, as shown in Fig. 5, by means-ofatoothed pawl .33. Said pawl 33 is held in active position, asshown in5, by means of .a -compression spring .25, )which rests upon said baseplate22. To opensaid bottom 9, said DaWlBSis releasedby the foot of saidporter inchargaupon the vextension 2-1 of said pawl 3.3 as .the .Weightof said bottom 9 depresses itheend of said lever I4 that retains, theupper vend of said shaft ylll. The weightof said porters foot may beadded when necessary. Said shaft l and thereby said bottom 9.a.repositioned exactlyfbythe adjustment plate Il in the following manner:The screws or bolts 3B. 3| are loosened and said plate l1 turned untilsaid bottom 9 is in thecorrect closed position and then said fastenings30, 3| are secured.V lSaid base plate 22 ,is securedto the floor 3..ofsaid portable toilet room in a common manner by .bolts .and

screws.

To 1provide for the need for emergency use of .a portable toilet whilethe vehicle bearing thesame is stopped at a station .requiresstructuralmeans that do not .interfere with standard `structures of thevehicle to which said means maybe applied .1. vrA -cess tank .for`toilets .having `-depending The vstructural means Ito meet these re'-drain spouts and supported upon a vehicle comprising a tubular tankpositioned vertically beneath the toilet drain spout and attached to theunderside of the vehicle supporting means for `the toilet with whichsaid tank is associated, a bottom for closing the lower end of saidtank, a tube mounted on the side of said tank and extendinglongitudinally thereof, a shaft rotatably and slidably positionedthroughsaid tube, an arm extending from' the flowerrendof said shaft tobeneath said tank and supporting said bottom, said shaft being formedwith a screw portion, a base .plate xedly mounted on the top of saidvehicle supporting means and having an opening formed therethrough, anut adjustably mounted on said base plate with the bore of said nutbeing in line with ,said base plate opening and the bore of said tubeand having said shaft slidably mounted through said plate opening andsaid nut bore, the screw part ofl said shaftv being arranged forthreaded engagement with said nut during part of the-movement of saidshaft for .rotating the same, a' lever pivotally -mounted on said baseplate and .pivotally conected at one end to the LOD of said shaft forraising and lowering said shaft, and` ,locking means `forretaining saidlever in various-.positions as desired.
